(6) Codes transmitted
(7) Data format
Format
F (default)
Selecting a data length of 7 bits allows you to transmit alphanumerical characters
and symbols but inhibits you from transmitting punctuation characters and using
2-byte codes to send dedicated characters and user pattern characters.
(8) Bit configuration
Formats A and B
Start b b
0 1
Formats C and D
Start b b

Order of code transmission: Transmission occurs beginning with the least significant bit (b0).
(9) Error control
● Vertical parity error (detection on an individual character basis)
● Overrun error
● Framing error
: Half duplex
: Started up by host
: Asynchronous
: Bit serial transmission
: 150, 300, 600, 1,200, 2,400, 4,800, 9,600, 19,200, 38,400,
57,600, 115,200(bps)
: Alphanumerical characters, symbols, dedicated characters,
user pattern characters, and punctuation characters
: Formats A through J are selectable (see the table below).
No other formats can be chosen.
